Pros and cons of permanent magnet motors

Greetings all
Pros and cons of permanent magnet motors

What uses will the permanent magnet motors have when we finish our discoveries?

What disadvantages would there be in industrial use?

How large can we make them before the magnetic field become more of a danger?

These questions I feel are in good timing to what we are doing. I can see allot of advantages in small application or magnet wheels, even up to car motors. But I see disadvantage to large industrial use. First getting magnets big enough and then the difficulty of using them or even making them ( basically dealing with them ). Imagine 2 strong magnets just 3 foot tall and you are having to place them in some equipment. The magnetic field would be massive and you have to think. What can it do to me, or what happens if they attract and you are in between them?

Just a little food for thought and I think good for discussion.

If we can build spaceships, large supertankers and other heavy duty devices, then the safe handling of big
supermagnets is entirely an engineering task. This will not be a limiting factor in design and production.

Greetings Honk

 The biggest problem with large magnets are, what do we have to do? And what kind of equipment will be able to work with them? It will be interesting on how it may be done.

Lets go hypothetical. A 1ton magnet that has a constant strong draw. What do we know of today that can lift it and move it around without getting stuck on it? Then we have to mount it in something. Are we going to have limits to what may be to hot to handle so to speak? Aluminum seems to be the best idea that I can think of, but just working with small magnets there is a problem keeping them from attracting to each other while working on a wheel. This is where the real problem comes in. IMO

PS I use to be in the Coast Guard and I have been ship yards as well. It is not as massive as one might think moving large tankers. It is the cranes and the moving platforms otherwise it is allot of men and women putting on one part at a time, like a large puzzle.

It seems to me that permanent magnets would only be useful in a few situations.  Yes, they can pull things together, but it takes an equal amount of energy to pull those things apart later.  Usually, an electromagnet is much more useful, because it can be turned off and on at will.

The problem is that we already have a constant force in place that needs to be overcome all the time.  That force is gravity.  Do we really need another one like that?

Gravity is a one way directional force, always pulling downwards on all subjects, no matter what.
You cannot arange the force of gravity into circular gradient force like within a magnetic wankel motor.
This is where magnets excel over gravity.

Hi,

one point I would like to bring forward.

Gravity is a minor force easily defeated with a circular balanced rotor.

Take care,

Michel

LOL Michelinho

You don't like gravity wheels. Do You? LOL
You will feel funny when a gravity powered device flies over you head. Lets keep an open mind here. This string is for magnet motors. To talk about how far do we think we can take them, and what will it take to work with them? Hypothetical of course at this stage. But please let your imaginations run free, that is what will make or break this string.

Well one of the pros I see, are low power magnet motors being used for kinetic sculpture art then becoming perpetual kinetic sculpture art  ;D. This is one of my favorites me being a blacksmith. I am already starting to design what I want to do for my art pieces.

These questions aren't really relevant because no one has built a fully permanent magnet motor that operates differently from the standard electric motors.  Even the wankle motor has an electromagnet in it - which puts it in the same category as a conventional motor.

Except that it is not possible do make perpetual motion from permanent magnets.  Magnetism is a force, not an energy being emitted.

Hi all,

A magnetic motor would have a chance to make the mainstream if it uses mirror image magnets. Attraction and Repulsion would not impede a free rotation like a regular magnet. According to Howard Johnson work on mapping magnetic vortices on magnets. Take a look. How to make those? Why they don't exist for us? Is it possible to make them? Just a thought.  ???

Take care,

Michel

But the real question is what powers the continual magnetic force in a magnet?

Lets think Newton.

For every action there is an equal and opposite reaction. Magnets are called a force, they attract and repel each other depending on the poles. So lets look on how this works into a possible magnet motor. Your action is an attraction the opposite pole is an equal and opposite reaction then they hold, Now your action is repel, the same pole repels and they keep apart due to it. So you look at each effect and you can have a push pull. One magnet attracts to one and then repels the other.  Simple logic says that it is possible to work with but there is allot to understand  about the magnet reactions. Back in 1974 I built one that ran for a day and a half, before my cardboard tore out in the middle. It was jerky due to the sticky spots but it tended to push by some how. My father put it down always saying it has already been done. I got an A for science and since I didn't support I took the magnets off and thought nothing more about it back then. So I know a magnet wheels can work. I learned that If my older brother came up with it, my dad would have announced it to the world, but I came from a family where the oldest could do no wrong and the youngest could do no wright.  :'(

Thats a sad story.  Do you remember the configuration of the magnets?  Just rebuild it.

That was a long time ago but I do remember part and pieces and have been playing it from time to time. I will tell you this that there where 3 pushes to each sticky spot and that is what made the jerking action. The reason I haven't pushed to hard on trying to duplicate it is I have been working on how to nullify the sticky spots to a minimum or all together by field manipulation. And it has been allot of fun. One of my manipulation test made like a pop action and shot the center disk around for a short ways. So I put 3 on the center disk with the one on the side and it shot kind of pop pop pop action but no real sound. but they where still a little to far apart to keep it running. So the next test will be 6 and that should do it. Now you can see I am not saying what configurations I am using, at least not until I have finished.
